I've read both
Topper and the
Night Life of the Gods. I found the latter funnier and more entertaining. I won't use up a vote to second
Night Life of the Gods, but if it eventually makes it to the vote I will happily vote for it.
I would like to nominate
Carmen by Prosper Mérimée. This is the book upon which the Bizet opera was based.
Here is the epub that actually includes three other stories by Mérimée.

Here is a the Carmen alone as a mobi file.
